PHP _tag_options函数代码示例

/**
 *
 * Creates a link tag of the given +name+ using an URL created by the set of +options+. See the valid options in
 * the documentation for ActionController::Base#url_for. It's also possible to pass a string instead of an options hash to
 * get a link tag that just points without consideration. If nil is passed as a name, the link itself will become the name.
 *
 * The html_options has three special features. One for creating javascript confirm alerts where if you pass :confirm => 'Are you sure?',
 * the link will be guarded with a JS popup asking that question. If the user accepts, the link is processed, otherwise not.
 *
 * Another for creating a popup window, which is done by either passing :popup with true or the options of the window in 
 * Javascript form.
 *
 * And a third for making the link do a POST request (instead of the regular GET) through a dynamically added form element that
 * is instantly submitted. Note that if the user has turned off Javascript, the request will fall back on the GET. So its
 * your responsibility to determine what the action should be once it arrives at the controller. The POST form is turned on by
 * passing :post as true. Note, it's not possible to use POST requests and popup targets at the same time (an exception will be thrown).
 *
 * Examples:
 *   link_to "Delete this page", { :action => "destroy", :id => @page.id }, :confirm => "Are you sure?"
 *   link_to "Help", { :action => "help" }, :popup => true
 *   link_to "Busy loop", { :action => "busy" }, :popup => ['new_window', 'height=300,width=600']
 *   link_to "Destroy account", { :action => "destroy" }, :confirm => "Are you sure?", :post => true
